Embodiment
In order to be better understood from the present invention, below in conjunction with the accompanying drawings with the embodiment content that the present invention is furture elucidated, but this The content of invention is not limited solely to the following examples.
Fig. 1 is the casting blank crack line figure caused by non-uniform spraying, although it will be seen from figure 1 that underbead crack is very serious, But it is smaller and short on pattern, there is segregation phenomena in the middle of crackle, hence it is evident that be crackle caused by process of setting thermal stress.This kind splits The quality and performance of the serious influence steel billet of line meeting.It is this with the raising of pulling rate in traditional aerial fog nozzle steel alloy casting machine Crackle is very common;In the full (operating) water nozzle design of high pressure, with regard to 150*150 small billets, once straight carbon steel pulling rate is more than 3.4m/min, product It is more common that kind of pulling rate is more than this middle crack in 2.5m/min, strand, and is difficult to be completely eliminated.
Fig. 2 is to cause traditional cold water spray system schematic of small billet variety steel casting machine two of above casting blank crack line, and it sprays Mouth is using the oval of small water or bores nozzle entirely, and due to the limitation of bleed type, nozzle footprint is smaller, and it is on strand Not overlapping between the spray spot of formation ellipse, as shown in figure 3, there is water spray area and the area that do not spray water, this necessarily brings cold But inequality.In the case of low pulling rate, strand temperature is relatively low, and this uneven temperature difference brought is also little, and strand inside is split The generation influence of line is smaller, once pulling rate is improved, strand temperature is improved, and the temperature difference in water spray area and the area that do not spray water is increased rapidly, different Normal thermal stress occurs, and causes the generation of crack of billet.
It can also be seen that the fixation of traditional spraying rack is closely related with carrying roller position from Fig. 2, spraying rack is seated in two On carrying roller, the fixing equipment of such spraying rack is relatively simpler and easily realizes, but causes a section spraying rack or shower very Long, typically in more than 2m, even up to 2.8m, spraying rack own wt is heavier, and installation is not easy to, simultaneously because spraying rack Long, after when nozzle spray, decline of pressure is obvious, it may appear that spraying rack upper end nozzle is bad due to the inadequate spraying effect of pressure Situation, situation about not spraying water even so that can not all be realized along the continuous of the strand on throwing direction in a spraying rack Cooling.
To solve the above problems, the technical solution adopted by the present invention is:As shown in figure 4, being drawn for billet caster height Two cold water spray equipment of fast-growing production include more piece spraying rack 1, and often saving the spraying rack 1 includes many showers 2, the shower 2 four directions all around that are symmetrical and being evenly provided on continuous casting billet.The big nozzle 3 of aerosol, institute are provided with the shower 2 The water outlet normal of the big nozzle 3 of aerosol is stated perpendicular to the axis of continuous casting billet.It is in opposite direction in the two cold water sprays equipment and throwing One end, the front and rear edges for the adjacent spray spot 4 that the big nozzle 3 of aerosol is formed on continuous casting billet is all overlapped, adjacent The water that the big nozzle 3 of two aerosols is sprayed onto on continuous casting billet surface is arranged in continuous.Draw on height edge of the big nozzle 3 of aerosol away from continuous casting billet Base direction is gradually reduced so that be changed into part mutually along the front and rear edges of the adjacent spray spot 4 in throwing direction from all overlapped It is overlapping, while ensureing that the overlay area of spray spot 4 on the strand width vertical with throwing direction is gradually reduced.
The big nozzle 3 of aerosol is flat or rectangle aerial fog nozzle, and forms on continuous casting billet that corner is round and smooth does not advise Then rectangle sprays spot 4, as shown in figure 5, the short side of two adjacent rectangles spray spot 4 coincides completely or partially.The big spray of the aerosol Mouth 3 it is wide to spray angle up to 85~110 °, it is narrow to spray angle be 20~40 °, it is described wide to spray angle and narrow to spray Firing angle degree can be by controlling hydraulic pressure to change within the above range, and hydraulic pressure can be 0.8~2.0MPa.The big nozzle 3 of aerosol with It is wide to be evenly arranged to angle along throwing direction on the shower 2, the distance between two adjacent big nozzles 3 of aerosol be 350~ 500mm.The big nozzle 3 of identical or varying number aerosol can be set on the shower 2 of each four direction of spraying rack 1.By Have certain radian in whole spraying rack, on the shower 2 of the interior outer arc in knee the quantity of the big nozzle 3 of aerosol it is few, Spacing is big, and the quantity for being located at the big nozzle 3 of aerosol on the shower 2 of the left and right side of spraying rack 1 is more, spacing is small.
The big height of the nozzle 3 away from continuous casting billet surface of aerosol is 200~300mm, and is gradually reduced along throwing direction.This It is because along throwing direction, the temperature of continuous casting billet gradually lowers, in order to prevent from spraying the steel billet supercooling of the overlapping of spot 4, described Adjacent spray spot 4 of the two cold water spray equipment along throwing direction one end overlapped, corner only in the center section of the short side Point no longer overlap, and the overlay area of spray spot 4 is gradually reduced on the strand width vertical with throwing direction.So can be After Casting speed is improved, preferable cooling uniformity is still kept, minimum thermal stress is produced, so that avoiding the occurrence of thermal stress causes Middle crack.
Fig. 4 and Fig. 6 respectively illustrate two kinds of fixed forms of spraying rack 1.As shown in figure 4, the fixing point of epimere spraying rack For a and b, a is taken root from base, and b is located at spraying rack upper right side, but takes root still from same a identicals base, generates a hook housing, Fixed mount as b.The fixing point a and b of spraying rack are taken root from adjacent base in Fig. 6, are all located at the lower section of spraying rack, A is located at below spraying rack entrance, and b is located at spraying rack and exports lower section.This two kinds of structure designs cause fixation and the tradition of spraying rack 1 Carrying roller is decoupled, using more flexible fixed form, makes the single length of shower 2 shorter and the convenient regulation of length, and this design is fine Solve the problem of spraying rack upper nozzle pressure is low.Even if using 2 two spraying racks of spraying rack public one of this form Individual water valve is also not in the situation of upper nozzle insufficient pressure, is that a kind of achievable valve is few and cooling zone very long method, institute The total length of spraying rack 1 is stated up to more than 8m.
Using the two cold water spray equipment of the present invention for the high pulling rate production of billet caster, for cross dimensions For 150 × 150mm strand, the pulling rate of variety steel is 2.8~3.6m/min, and the pulling rate of straight carbon steel is 3.5~4.0m/min.It is right In the strand that cross dimensions is 160 × 160mm, the pulling rate of variety steel is 2.6~3.6m/min, the pulling rate of straight carbon steel for 3.2~ 4.0m/min.It can be seen that, the pulling rate of variety steel and straight carbon steel is greatly improved.
